Writing Quality Tests - 3T Jitter Tests

As was mentioned before, the Artec drive supports 24x maximum writing speed. We burned three Taiyo Yuden media, in order to test the writing quality at all the available writing speeds.

- 3T Pit results

At all speeds, the Artec drive overshoots the 35ns RedBook limit, with 12x being the worst.

- 3T Land results

Again, at all speeds the drive goes over the 35ns level, although with 16x and 24x the performance is a little better. Certainly, 12x appears to not give such good results.

Recording Speed	Average 3T Pit Jitter (ns)	Average 3T Land Jitter (ns)	> 35ns	Max 3T jitter values (ns)
12X	35.80	37.05	Yes	38 Pit, 40 Land
16X	34.00	33.32	Yes	37 Pit, 36 Land
24X	34.51	33.34	Yes	36 Pit, 36 Land

Generally, the drive revealed consistent writing quality and although the 35ns mark was breached, with 16x and 24x it is not by much for both Pit and Land jitter. The 12x levels are slightly high, so it may be advisable to avoid writing at this speed.
